Applied systems thinking: a viable approach to identify leverage points for accelerating progress towards ending neglected tropical diseases.

BACKGROUND: Systems thinking is a conceptual approach that can assist stakeholders in understanding complexity and making progress on persistent public health challenges. Neglected tropical diseases (NTDs), a complex global health problem, are responsible for a large disease burden among impoverished populations around the world. This aim of this study was to better discern the many complexities of the global NTD system in order to identify and act on leverage points to catalyse progress towards ending NTDs. METHODS: Existing frameworks for systems change were adapted to form the conceptual framework for the study. Using a semi-structured interview guide, key informant interviews were conducted with NTD stakeholders at the global level and at the country level in Nigeria. The interview data were coded and analysed to create causal loop diagrams that resulted in a qualitative model of the global NTD system. RESULTS: The complete qualitative model is discussed and presented visually as six separate sub-components that highlight key forces and feedback loops within the global NTD system. CONCLUSIONS: We identified five leverage points for NTD system change, namely (1) clarify the potential for and assess realistic progress towards NTD elimination, (2) increase support for interventions besides drug delivery, (3) reduce dependency on international donors, (4) create a less insular culture within the global NTD community, and (5) systemically address the issue of health worker incentives. The specific findings for NTDs raise a number of uncomfortable questions that have not been addressed, at least in part, because it is easier to continue focusing on 'quick win' solutions. The study provides a model of a systems thinking approach that can be applied to other complex global health and development challenges in order to understand complexity and identify leverage points for system change.

International cooperation to improve access to and sustain effectiveness of antimicrobials.

Securing access to effective antimicrobials is one of the greatest challenges today. Until now, efforts to address this issue have been isolated and uncoordinated, with little focus on sustainable and international solutions. Global collective action is necessary to improve access to life-saving antimicrobials, conserving them, and ensuring continued innovation. Access, conservation, and innovation are beneficial when achieved independently, but much more effective and sustainable if implemented in concert within and across countries. WHO alone will not be able to drive these actions. It will require a multisector response (including the health, agriculture, and veterinary sectors), global coordination, and financing mechanisms with sufficient mandates, authority, resources, and power. Fortunately, securing access to effective antimicrobials has finally gained a place on the global political agenda, and we call on policy makers to develop, endorse, and finance new global institutional arrangements that can ensure robust implementation and bold collective action.

Strategies for achieving global collective action on antimicrobial resistance.

Global governance and market failures mean that it is not possible to ensure access to antimicrobial medicines of sustainable effectiveness. Many people work to overcome these failures, but their institutions and initiatives are insufficiently coordinated, led and financed. Options for promoting global collective action on antimicrobial access and effectiveness include building institutions, crafting incentives and mobilizing interests. No single option is sufficient to tackle all the challenges associated with antimicrobial resistance. Promising institutional options include monitored milestones and an inter-agency task force. A global pooled fund could be used to craft incentives and a special representative nominated as an interest mobilizer. There are three policy components to the problem of antimicrobials--ensuring access, conservation and innovation. To address all three components, the right mix of options needs to be matched with an effective forum and may need to be supported by an international legal framework.

Les dysfonctionnements de la gouvernance et du marché à l'échelle mondiale se traduisent par une impossibilité de garantir l'accès à des médicaments antimicrobiens durablement efficaces. De nombreuses personnes s'emploient à pallier ces dysfonctionnements, mais leurs institutions et leurs initiatives manquent de coordination, de direction et de moyens financiers. La création d'institutions, l'élaboration de mesures d'incitation et la mobilisation des parties intéressées font partie des options possibles pour promouvoir une action collective mondiale sur l'accès aux antimicrobiens et sur leur efficacité. Aucune option isolée ne suffira à venir à bout de tous les problèmes associés à la résistance aux antimicrobiens. Parmi les options institutionnelles prometteuses, il convient de mentionner le suivi des étapes importantes et une équipe spéciale interorganisations. Des fonds mis en commun à l'échelle mondiale pourraient être utilisés pour élaborer des mesures d'incitation et un représentant spécial pourrait être chargé de mobiliser les parties intéressées. Le problème des antimicrobiens comporte trois aspects stratégiques: garantir l'accès, la conservation et l'innovation. Pour agir à l'égard de ces trois aspects, il est nécessaire d'associer les options, harmonieusement combinées, à une structure efficace et, peut-être, de les inscrire dans un cadre juridique international.

Los fracasos de gobernanza mundial y de los mercados significan que no es posible garantizar el acceso a medicamentos antimicrobianos de efectividad sostenible. Muchas personas trabajan para solucionar estos problemas, pero sus instituciones e iniciativas no están lo suficientemente coordinadas, guiadas y financiadas. Las opciones para promocionar una acción colectiva global en cuanto al acceso a los antimicrobianos y la efectividad incluyen la creación de instituciones, la elaboración de incentivos y la movilización de intereses. Ninguna opción por sí sola es suficiente para afrontar todos los desafíos asociados con la resistencia a los antimicrobianos. Las opciones institucionales prometedoras incluyen hitos supervisados y un grupo de acción interinstitucional. Se podría utilizar un fondo combinado global para elaborar incentivos y nominar un representante especial como un movilizador de intereses. El problema de los antimicrobianos tiene tres componentes de las políticas: asegurar el acceso, la conservación y la innovación. Para abordar los tres componentes se necesita que la mezcla correcta de opciones se una a un foro efectivo, y podría necesitar el apoyo de un marco legal internacional.

Universal Access to Effective Antibiotics is Essential for Tackling Antibiotic Resistance.

Universal access to effective antimicrobials is essential to the realization of the right to health. At present, 5.7 million people die from treatable infections each year because they lack this access. Yet, community-based diagnosis and appropriate treatment for many of the leading causes of avoidable infectious deaths has been shown to be feasible and effective, demonstrating that strategies to reach the under-served need to receive high priority. This is a necessary part of a broad strategy to assure the long-term benefits of antimicrobials and to combat antimicrobial resistance, both because the lack of systematic and rigorous efforts to assure effective coverage increases the likelihood of antimicrobial resistance, and because global efforts aimed at antimicrobial stewardship and innovation cannot succeed without explicitly addressing the needs of the under-served. Elements of this strategy will include clear evidence-based treatment protocols, a robust international framework and locally tailored regulations, active engagement with communities and local health providers, strong attention to program management and cost considerations, a focus on the end user, and robust surveillance and response to emerging resistance patterns. Only by balancing the needs of universal access with stewardship and innovation, and assuring that they are mutually reinforcing can a global strategy hope to effectively address antimicrobial resistance.

The Global Health Strategy of the Department of Health and Human Services: building on the lessons of PEPFAR.

Building on its experience as a principal participant in the President's Emergency Plan for AIDS Relief, the Department of Health and Human Services has embarked on a new era of global initiatives that ultimately will protect the health of Americans. The Global Health Strategy announced by health and human services secretary Kathleen Sebelius in January 2012 recognizes that the health of Americans is intertwined with that of the rest of the world. The initiative features ten objectives that range from enhanced global health surveillance and preventing infectious diseases and health threats to health diplomacy. The Global Health Strategy is designed to make optimal use of the department's many specialty agencies and their considerable technical and programmatic expertise. The strategy moves beyond the President's Emergency Plan for AIDS Relief to redefine Health and Human Services' role outside US borders in addressing the health challenges of the twenty-first century.

Global health for a globally minded president.

President-elect Barack Obama can build on historic initiatives championed by his predecessor in global AIDS and malaria. These should serve as the platform for a more comprehensive and evidence-based set of activities aimed at addressing the major causes of ill health and instability in low-income countries. Obama should launch a new Global Family Health Action Plan aimed at saving the lives of six million children and women annually in impoverished nations. Existing policies driven by U.S. domestic ideological battles, particularly those relating to sexual and reproductive health, should be revised and brought into line with solid science and evidence from the field.

Beyond trade: taking globalization to the health sector.

The pace of globalization has brought the world to the brink of a new era in international relations. While the world has outgrown traditional mechanisms for addressing global issues, it has not yet developed new forms of effective governance. This temporary void poses threats and enormous opportunities. The public health sector will play a crucial "formal" role--that is, carried out by existing bodies such as WHO and the UN. But WHO does not necessarily represent the full spectrum of views and its members necessarily work, to some degree, for separate national interests. The formal dimension must be supplemented. Globalization is not synonymous with lack of regulation. Many responsible businesses would welcome a transparent and universally applied regulatory regime to prevent a race to the lowest standards. The economic benefits of globalization may hit a glass ceiling if societies outside the global economy become progressively poorer and less healthy. The business community is recognizing that good health is essential for economic growth and social stability. Globalization may cause millions to migrate for economic opportunity. The private sector's forward-thinkers recognize the health threats of migration and are beginning to view global health promotion as a means to ensure optimal market access.
